Bit 6D/A Output Enable 0 (DAOE0): Controls analog output from the D/A converter.
Bit 6
DAOE0 Description
0 Analog output at DA
0
is disabled.
1 D/A conversion is enabled on channel 0. Analog output is enabled at DA
0
.
Bit 5D/A Enable (DAE): Controls analog output from the D/A converter, in combination with
bits DAOE0 and DAOE1. D/A conversion is controlled independently on channels 0 and 1 when
DAE = 0. Channels 0 and 1 are controlled together when DAE = 1.
Whether or not to output the converted results is always controlled independently by DAOE0 and
DAOE1.
Bit 7
DAOE1
Bit 6
DAOE0
Bit 5
DAE D/A conversion
00Disabled on channels 0 and 1.
0 1 0 Enabled on channel 0.
Disabled on channel 1.
0 1 1 Enabled on channels 0 and 1.
1 0 0 Disabled on channel 0.
Enabled on channel 1.
1 0 1 Enabled on channels 0 and 1.
11Enabled on channels 0 and 1.
When the DAE bit is set to “1,” analog power supply current drain is the same as during A/D and
D/A conversion, even if the DAOE0 and DAOE1 bits in DACR and the ADST bit in ADSCR are
cleared to “0.”
Bits 4 to 0Reserved: These bits cannot be modified and are always read as “1.”
